How to Use

1. Starting a session

1.1. From the session picker screen press the start button.

1.2. The session in-progress screen contains the following elements

• time elapsed arc

  • each marked position corresponts to an alert trigger time
  • you can hide them per alert by selecting transparent color from the Interval Alerts settings menu
• time elapsed
• current HR
• current HRV Successive Difference
  • difference between the current and previous beat-to-beat intervals measured in milliseconds
  • shows only when HRV tracking is on
  • to get good HRV readings you need to minimise wrist movement

The meditation session finishes once you press the stop button. The meditation session can be paused/resumed using the back button.

1.3. Once you stop the session you have the option to save it.

1.5 If you are in multi-session mode (determined by Global Settings -> Multi-Session) then you go back to the session picker screen. From there you can start another session. Once you finish your session you can go back from the session picker screen to enter the Sessions Summary view.

1.6 From the Sessions Summary view you can drill-down into individual sessions or exit the app. Drilling-down shows summary stats of HR, Stress and HRV. If you go back from the Sessions Summary view you can continue doing more sessions.

2. Configuring a session

2.1 From the session picker screen hold the menu button until you see the Session settings menu.

• for Vivoactive 3 hold on the screen
